DETACHABLE SPOUT FOR CONTAINERS Filed Jan. 3, 1938 2 Sheets-Sheet 2 6 vJOSEPH B ENGLERT INVENTOR Pl 5 6 ATTORNEY Patented June 4, 1940 UNITEDSTATES PATENT OFFICE ll Claim.

This invention relates to improvements in detachable spouts forcontainers and while intended for use generally on any form of containerto which it may be advantageously applied, it is particularly applicableas an improvement in spouts for milk bottles in which connection it willbe illustrated in the drawing and hereinafter described.

Objects of the invention are to provide a spout of simple, durableconstruction, which may be manufactured at a low cost, which will fitbottles or other containers of different shapes and sizes; which may bequickly and conveniently positicned on a container or removed therefrom;which may be easily cleaned or sterilized and which will be veryeflicient in use.

Other objects are to provide a closure member for bottles and othercontainers which will be composed of one piece of elastic materialarranged to fitsnugly about the mouth of a bottle or other container,and which is provided with a self-closing spout arranged to permit thepouring of liquid from the container without spilling or otherwisewasting the liquid.

An additional object is to provide a spout composed of one piece ofelastic rubber, with a lug forming a handle portion and arranged to holda bottle cap during the pouring operation.

The above and additional objects are attained by the novel constructionhereinafter described with reference to the accompanying drawingswherein there is shown a preferred form of the invention, it beingunderstood that the invention may be adapted in various ways to variousforms of containers and that changes and modifications may be made whichcome within the scope of the appended claim. e

In the drawings:

Figure 1 is a side elevational view showing the upper portion of. a milkbottle with a closure member constructed in accordance with thisinvention operatively positioned thereon,

Figure 2 is a central, vertical view of same taken as indicated by thelines 2-2 of Figure 3,

Figure 3 is a top plan view of same,

Figure 4 is a side elevational view of the upper portion of a containershowing an adaptation of the invention in which the top wall is omitted.

Figure 5 is a top plan view of same,

Figure 6 is a vertical, sectional view taken as indicated by the lines6-6 of Figure 5.

Proceeding now to a detailed description of the invention with referenceto the particular adaptation thereof. illustrated in the drawing, thenumeral 6 is used generally to denote a bottle or other container. Thebottle 6 is provided around the top thereof with the usual flange 1which in the particular bottle shown in the drawings is of rounded crosssectional shape. The mouth of the bottle 6 is enlarged at the outer 5end thereof to provide a shoulder 8 which supports the closure capordinarily used in covering the mouth of the bottle.

A cap constructed in accordance with this invention is molded orotherwise formed of one 10 piece of rubber and is provided with a baseportion 9 which is in the form of a band adapted to fit around theflange 1. The band 9 is preferably bulged outwardly to conform in shapeto the flange I and is normally smaller than the flange 15 I on which itis to be positioned. A spout it projects upwardly from one side of theflange i.

The spout l0 conforms in shape to a portion of a wall of a hollowcylinder and is arranged with the upper edge thereof inclined downwardly20 toward the central portion of the bottle.

The numeral ll denotes a top wall which is a continuation of the base 9.A portion of the top wall H extends straight across the mouth of. thebottle and is continued upwardly to form the in- 25 clined flap [2. Theflap I2 is formed to be normally positioned against the upper end of thespout I0, whereby the elasticity of the material of which the cap iscomposed will normally hold the flap [2 in a closed position. The flattop portion II is provided with an aperture l3.

The numeral I5 denotes a flap which is composed of elastic rubber and issecured to the top Wall II at a point spaced from the aperture [3 withthe free end of the flap covering the aperture I3 whereby air will beadmitted to a bottle to cause a smooth flow of liquid from the spoutIll. The flap l5 covers the aperture when the container is in an uprightposition to exclude dirt, dust or other objectionable substances fromentering the said aperture.

In the modification of the invention shown in Figures 4 and 5 and 6, thetop wall I l and the lid I2 are omitted thereby forming a detachable 45spout which may be positioned on a milk bottle or similar containerwithout interfering with the use of the ordinary closure disk.

The ring 9 is provided on the outer side thereof at a point directlyopposite thespout H! with an 5 integrally formed lug it which projectsradially therefrom- The lug i6 is provided with a vertical slot ll forreceiving and holding a disk ordinarily used as. a closure member. Theportion l6a of. the lug I6 projects upwardly to form a handle 55 whichmay be used in placing the spout on a bottle and in removing the sametherefrom.

The ring 9 is preferably provided with an outwardly projecting annularbead I8 on the lower edge thereof which is formed thereon to strengthenthe lower edge thereof and to provide means for more securely holdingthe ring in an operative position on a container.

In use, the base portion 9 is stretched over the flange 1 of a bottle orother container with the spout II in the position shown in the drawings.As the structure herein disclosed is composed entirely of elasticrubber, it will be securely held in position on the container and willprovide efiicient means through which liquid may be poured from thebottle without spilling. The flap l2 being formed of elastic rubber willbe forced open by the weight of the liquid to be poured. The flap I5 isin a position where it can in the form of a flap.

readily be manipulated to admit air to the bottle during the pouringoperation. If desired, pressure may be applied to the lid l l or to thelower I thereof, and an integrally formed top wall on said base, saidtop wall extending over said spout JOSEPH B. ENGLERT.
